Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To rewind a film, at least following the winding of the film at idly feeding the film, in order to write magnetic information on the film without causing irregularities in film running at writing the information. SOLUTION: A photographing enabling frame number information display on a film cartridge 10 is read by a bar bode sensor 15. The film 12 is mound around a wind spool 11 by the driving force of a motor MB 7 and a motor drive circuit 5, and at loading the film cartridge 10, a film leader part is fed out at a speed lower than a film wind speed by the driving force of the motor MA 6 and the motor drive circuit 3 so as to wind up the film around the wind spool 11. And also, in operation of winding the film 12, information is magnetically recorded on the magnetic track of the film 12 by the use of the magnet head 18.  In the case that the read number of photographing enabling frames is smaller than a prescribed value, after winding the film up to the prescribed number of frames exceeding the first photographing frame position once after winding the film leader part on the wind spool 11, the film is driven is driven in the rewinding direction, and then the position of the first photographing frame is searched.

Title: Manufacture of magnetic molded body having hollow part
Inventor: MATSUZAWA HIDEKI
IPC: B29C48/355
Filed: 1990-01-11
Abstract: PURPOSE:To manufacture an extrusion molded body without deforming the same by passing the hollow magnetic molded body extruded from a mold between a pair of opposed conveyors and feeding the same by the conveyors while the surfaces opposed to a pair of the conveyors are respectively magnetically attracted to the conveyors. CONSTITUTION:The magnetic molded body 4 immediately after kneaded and extruded by an extrusion molding machine 1 is in such a state that it is not sufficiently cooled and solidified and, when the shape thereof is not held by any method, the upper part of the magnetic molded body 4 is in a state generating deformation under its own wt. As a measure to prevent this state, magnets 32 are respectively arranged to the insides of the belts 31 of respective conveyors 3. Since the mutually opposed surfaces of the magnetic molded body 4 composed of a magnetic powder are respectively attracted in upper and lower directions by a pair of the magnets 32 to be adsorbed on the belts, the magnetic molded body 4 is guided and taken up by the belts 31 while the hollow part thereof is held without generating deformation under its own wt.

Title: Cooker
Inventor: TANABE TAKESHI
IPC: H05B3/00
Filed: 1979-01-11
Abstract: PURPOSE: To obtain detecting means suitable for cooking by providing plural kinds of detecting means and heating source controlling means connected with each detecting means via change-over switches.  
     CONSTITUTION: An oven/grill change-over knob is set on the oven side and all the change-over switches 14, 21, 25 and 26 are changed to the contact O side. By so doing, a thermistor 11 is connected with a comparator 16 and values detected by the thermistor 11 are compared with set voltage preset with a variable resistor 17. This set voltage corresponds to an oven chamber temperature suitable for food 3. Therefore, if a temperature detected by the thermistor 11 is lower than a set temperature, the comparator 16 excites a DC relay 18 noninverted, and if higher, disexcites the DC relay 18 inverted. By so doing, current flow through a sheath heater 5 is on-off controlled near the set temperature and the temperature in the chamber is kept at the set temperature.

Title: Endoscope
Inventor: SAKAMOTO NOBUYUKI
IPC: G02B23/24
Filed: 1988-01-11
Abstract: PURPOSE:To enhance operability by respectively controlling the jet amounts of the compressed air injected from a plurality of the jet orifices formed to an insert part to control the curving quantity of the insert part in a predetermined direction. CONSTITUTION:When an insert part 2 is curved downwardly, an up-and-down angle knob 9 is rotated in the left direction for example. Whereupon, the direction and angle of rotation of the insert part 2 are detected by the first encoder 23 and the signal corresponding thereto is inputted to the first controller 21. By this mechanism, the variable valve 17 of the first electropneumatic regulator 14 is moved in the right direction and the first port 16 is allowed to communicate with the second port 18. Therefore, since the compressed air from a compressor 12 is injected from the upper jet orifice 8a of the insert part 2 through the second port 18, the insert part 2 is curved downwardly by the reaction force thereof. The curved angle of the insert part 2 in the downward direction can be changed according to the jet amount of the compressed air injected from the upper jet orifice 8a.

Abstract: PROBLEM TO BE SOLVED: To prevent faulty electrification from occurring because residual toner on a photoreceptor drum left after transfer is mixed in magnetic particles in a contact electrifying device which uniformly electrifying the photoreceptor drum by allowing the magnetic particles carried on the surface of a developing sleeve to rub on the photoreceptor drum. SOLUTION: A non-magnetic electrifying sleeve 22 including a magnet 21 having plural magnetic poles is rotated in a direction shown by an arrow R22. The magnetic particles are carried on the surface of the sleeve 22, fed and allowed to rub on the surface of the photoreceptor drum, and simultaneously electrifying voltage is applied on the sleeve 22 so as to uniformly electrify the surface of the photoreceptor drum to specified potential. At the time of rubbing, the residual toner on the surface of the photoreceptor drum left after transfer is mixed in the magnetic particles carried on the sleeve 22. The magnetic particles in which the residual toner left after transfer is mixed fall off from the surface of the sleeve 22 by the repulsive poles of magnetic poles N2 and N3 having the same polarity and arranged adjacently to each other.  The new magnetic particles(in which the residual toner left after transfer is not mixed) stored in a storage container 25 are carried and fed on the sleeve 22, and the photoreceptor drum is electrified.

IPC: B29C51/00
Filed: 1980-01-14
Abstract: PURPOSE:To quicken the temperature rise and to facilitate the laminating operation, by arranging heat radiating lamps for heating a transparent film between delivering rollers for the transparent film and a card and pressure rollers. CONSTITUTION:An electric current is passed through the heat radiating lamps 17a, 17b, and at the same time the delivering rollers 15 and the pressure rollers 16 are rotated in the same direction. Especially, as heat radiating lamp, if infrared halogen lamps are used, the time required to make the laminating machine operable will be further shortened. Thus, after the switch is switched on, the layered card and transparent film can be inserted through the insert inlet 21 within several seconds. The layered card and transparent film inserted through the insert inlet 21 are delivered between a pair of the heat radiating lamps 17a, 17b by the delivering rollers 15, and is heated during the passage. By this heating the transparent film is welded onto the card, and subsequently is pressed against it tightly by the pressure rollers 16 to complete the lamination.

IPC: H01S5/183
Filed: 1984-01-09
Abstract: PURPOSE:To inhibit wavelength shift due to the variation in band gap based on temperature changes by obtaining specific wavelength selectivity by a method wherein a multilayer periodical structure of a semiconductor film having a thickness (1/4+m/2) times (where, m=0,1,...) as large as the intracrystal wavelength of a generated laser beam is formed in the crystal. CONSTITUTION:When a forward voltage is impressed across an anode 5 and a cathode 6, the first and second P<+> Inp layers 14, 15 and the second and third P<+> InP layers 17 and 18 are biased in reverse direction; however, a current path generates by tunnel effect, and current flows as broken line arrows I. Carrier inversion distributed regions 21, 22, and 23 are formed at the centers of the first, second, and third P type InGaAsP active layers 13, 16, and 19, respectively. Then, induced emission occurs and causes reflection at the junction planes between the first-third P<+> type InP layers 12, 15, and 18 and the first-third P type InGaAsP active layers 13, 16, and 19, resulting in multiplex reflection. The thickness of each layer becomes 1/4 of the intracrystal wavelength of light in order that with respect to each layer a reflected light and an incident light strengthen each other under the same phase in the crystal.
